VCT types
5.4.1
There are two types (VCT3A and VCT3B) and one type is selected depending on the relay
applications.
Note: VCT3A is selected for the IED hardware model GRE200-1 (which can be read from
an ordering code position "7" of hardware). Conversely, VCT3B is selected for the
model GRE200-2. Refer to
and see
VCT3A
(i)
Figure 5.4-2 shows VCT3A type, which agrees with five voltages and four currents inputs.
